I get GE 1200 series from them at under 5.00 including taxes
The Glass I get is from Adriatic Glass and Mirror, they carry .5" and .75" at unbeatable prices

Thanks for the info!
Does anyone have a good local source for the foam needed for this?
Try any upholstery place. I'm pretty sure it is the same stuff they use. C&M textiles on merivale was who we used.
Make sure it is not treated with anything like fire retardant.
Not sure, it is just something I heard.

I called them about it: no go :(
I think you can get it in Toronto.
You can probably contact Udo and ask him.
